-The enclosed two messages describe a bug in GNU diff 2.6 and 2.7 which
-may cause CVS to perform an erroneous merge.  You may wish to use GNU
-diff 2.5 or apply the patch supplied by Loren James Rittle below.  It
-would be nice to add this to the CVS testsuite, but I haven't done so
-because probably a lot of people who would like to run the testsuite
-are using the buggy diff.

-Subject: diffutils 2.7 -- diff3 merge bug
-Date: Tue, 29 Oct 96 17:02:54 CST
-
-I believe a change first introduced in GNU diff 2.6 causes diff3 sometimes
-to produce incorrect merges.
-
-Since this is a not a bug in CVS itself but can cause commits to CVS
-repositories to be incorrect, am warning info-cvs@prep.ai.mit.edu as
-well as reporting the bug to bug-gnu-utils@prep.ai.mit.edu.
-
-I am including a simple test case as well as some sample outputs from
-different versions of `diff' and `diff3' in the enclosed shar archive.
-In addition, the file DESCRIPTION in that archive describes the problem
-more fully.
-
-If anyone has any advice for how to fix or to work around this bug, I would
-appreciate it.  Using diff 2.5 seems like the most immediately obvious
-solution, but I don't know if it will introduce other problems.
-I do not understand the algorithms used by GNU diff well enough to suggest
-any patches.
-
-Unshar and enjoy.  ;-)

-Subject: Re: diffutils 2.7 -- diff3 merge bug
-
-Noah,
-
-I have seen the problem you discuss in your e-mail, however I fail to
-see how this situation is as critical as might be implied since it can
-never arise without at least some user involvement (an update that
-caused a merge is never automatically followed by a commit --- the
-user has a chance to inspect the merged file).  However, I will agree
-that I don't always look very closely at non-conflicted merges before
-checking them back in.
-
-You didn't give the exact CVS commands used to create a lossage,
-but I added the following to your Makefile, to help me see the problem
-in a CVS usage context:
-
-t-older: testcase-older
-	cp testcase-older t-older
-
-t-yours: testcase-yours
-	cp testcase-yours t-yours
-
-t-mine: testcase-mine
-	cp testcase-mine t-mine
-
-# Assume cvs-1.9
-cvs-test: t-older t-yours t-mine
-	rm -rf /tmp/cvs-test-root x x2
-	cvs -d /tmp/cvs-test-root init
-	mkdir x
-	cp t-older x/testcase
-	cd x; cvs -d /tmp/cvs-test-root import -m '' x X X1
-	rm -rf x
-	cvs -d /tmp/cvs-test-root co x
-	cvs -d /tmp/cvs-test-root co -d x2 x
-	cp t-yours x/testcase
-	cp t-mine x2/testcase
-	cd x; cvs ci -m ''
-	-cd x2; cvs ci -m ''
-	cd x2; cvs update
-	cat x2/testcase # at this point, user may commit blindly
-
-It looks like whomever added shift_boundaries() in analyze.c, which
-seems to be the source of the diff3 induced mischief, already provided
-a means to disable the boundary shifting optimization (at least with
-a recompile).
-
-Here is the patch I applied to diff to disable this (currently)
-overaggressive optimization:
-
-[ rittle@supra ]; diff -c analyze.c-old analyze.c    
-*** analyze.c-old       Wed Oct 30 14:10:27 1996
---- analyze.c   Wed Oct 30 13:48:57 1996
-***************
-*** 616,622 ****
-     but usually it is cleaner to consider the following identical line
-     to be the "change".  */
-  
-! int inhibit;
-  
-  static void
-  shift_boundaries (filevec)

-  
-! int inhibit = 1;

-Now, diff-2.7 with the above patch produces:
-

-
-A better solution might be to disable the boundary shifting code
-unless explicitly turned on via command line argument.  That way
-programs, like diff3, expecting unoptimized diff regions will work
-correctly, yet users can get smaller diffs, if desired.  The problem
-is that diff3 doesn't properly track changes once they have been
-optimized.
-
-BTW, I never did like the look of the `optimized diff regions', so I
-consider this a good change for other reasons... :-)
-
-Enjoy!

-* bcopy -> memcpy & friends.
-  ** done 12/18/93
-  
-* remove static buffers.
-* replace list & node cache with recursive obstacks, (xmalloc,
-  getnode, getlist)
-* check all io functions for error return codes.  also check all
-  system calls.
-* error check mkdir.

----
-Old notes...
-
-* All sizing limits are gone.  The rest of these items were incidental
-  in that effort.
-
-* login name from history was duplicated.  taught existing routine to
-  cache and use that instead.  Also add routines to cache uid, pid,
-  etc.
-
-* ign strings were never freed.  Now they are.
-
-* there was a printf("... %s ...", cp) vs *cp bug in history.c.  Now
-  fixed.
-
-* The environment variables TMPDIR, HOME, and LOGNAME were not
-  honored.  Now they are.
-
-* extra line inserted by do_editor() is gone.  Then obviated.  Editor
-  is now called exactly once per checkin.
-
-* revised editor behaviour.  Never use /dev/tty.  If the editor
-  session fails, we haven't yet done anything.  Therefor the user can
-  safely rerun cvs and we should just fail.  Also use the editor for
-  initial log messages on added files.  Also omit the confirmation
-  when adding directories.  Adding directories will require an
-  explicit "commit" step soon.  Make it possible to prevent null login
-  messages using #define REQUIRE_LOG_MESSAGES
-
-* prototypes for all callbacks.
-
-* all callbacks get ref pointers.
-
-* do_recursion/start_recursion now use recusion_frame's rather than a
-  list of a lot of pointers and global variables.
-
-* corrected types on status_dirproc().
-
-* CONFIRM_DIRECTORY_ADDS
-
-* re_comp was innappropriate in a few places.  I've eliminated it.
-
-* FORCE_MESSAGE_ON_ADD
-
-* So I built a regression test.  Let's call it a sanity check to be
-  less ambitious.  It exposed that cvs is difficult to call from
-  scripts.
